BUTTON.

Specification of Letters Patent.

Patented Oct, 8, 1907.

Application filed October 27, 1905. Serial No. 284,607.

Y To all whom it may concern:

Be it known that I, FRANK P. PFLEGHAR, a citizen of the United States,and a resident of New Haven,

in the county of New Haven and State oi' Connecticut,

h'ave invented a new and useful Improvement f in Buttons, oi which thefollowing is a specification.

My invention relates to a button and more particularly to a button forholding a vehicle curtain. securely fastened.

In vehicles provided with curtains exposed to great air pressure, forinstance, curtains on high speed auto'- mobiles, great difficulty isexperienced in holding the curtains securely fastened when lowered foruse, and, at the same time, providing for quickly and easilyunastening'the. curtain when it is desired to raise it out of use.

My present invention is directed to means for overcoming this ditlicultyand consists in a button comprising a stationary hollow stud over whichan eye in the curtain is passed, a bolt seated and movable transverselyin the said stud and a rotary key and eccentric extending into the studand engaged with the bolt for projecting the bolt laterally from thestud and withdrawing it.

In the accompanying drawings, Figure 1 is a iront view of a portion of acurtain with the button in locked position, Fig. 2 is a top plan view,Fig. 3 is an enlarged horizontal section in the plane of the line A-A oiFig. 1, Fig. 4 is an enlarged vertical section in the plane of the' linel3-B of Fig. 1, Fig. 5 is a similar view showing the button in unlockedposition, Fig. 6 isa back view of the stud showing the retaining springin position, Fig. 7 is a similar view with the retaining spring removedand showing the base of thev eccentric in operative position,- Fig. 8 isa rear end view of the key, Fig. 9 is a iront end view of the eccentric,Fig. I0 is a rear view of the locking dog or bolt in detail. Fig. 11 isa side view of the key in detail, and Fig. 12 is a side view of therotary disk.

The curtain is here represented by 1 and may be of any material such asis commonly used for the purpose.' It is provided with an eye 2surrounded by a metal gromet 3 for protecting its wall as is common.

The stationary stud which supports the movable parts ofthe buttonconsists oi a base plate 4 from which a hollow neck or barrel 5 extendsoutwardly for receiving the eye oi. the curtain. Transversely throughthe neck 5 there extends an opening 6 in which the locking bolt or dog 7is seated and in which the said bolt or dog has a sliding movement. Thebolt or dog 7 has its locking end partially cut away on the inner orrear side to afford an extended flat bearing 8 on the gromet and at thesame time to provide for the thickness oi the curtain without undulylengthening the neck of the stud, and the said bolt has its ends roundedto conform to the curved surface oi the neck 5 of the stud in which itis mounted. The bolt or dog is lurther provided with a transverse slot 9open to the rear and with a transverse slot l0 open to the front andmerging into the slot 9.

The hollow neck 5 oi the stud has mounted therein a rotary disk 11having a flanged base 12 and an eccentric projection 13 extending intothe transverse slot 9 in the bolt when the latter is in position in thestud.

The i'ianged base 12 is provided on its rear face with indentations 14,15, for the reception of a nose 16 of the retaining spring 17 to holdthe eccentric in its positions with the bolt 7 advanced and withdrawn.

The retaining spring 17 is located in a shallow recess 18 in the rearface oi the base 4 Of the stud, the said recess being convenientlyundercut at one end to retain the spring and a small screw 19 may beemployed.

The eccentric projection 13 is operated by means of a key 20 providedwith a central pin 2l which extends rearwardly through the disk whichcarries the eccentric 13 and has its rear end provided with a nut 21* tohold the key in position. The key 20 is further provided with a pin 22eccentrically set therein and extending rearwardly into the eccentricprojection 13. The key 2O is further preferably centered in the outerend of the neck 5 oi the stud by means of a 'short cylindricalprojection 23 on its inner or rear end which fits in a shallow recess 24inthe outer end of theneck. The maximum diameter of the key 20 isintended to be not materially greater than the maximum diameter of theneck 5 ofthe stud as the eye of the curtain is passed over the key aswell as over the stud in securing and releasing the Curtain.

In assembling the parts, the bolt 7 is irst placed in position in theopening 6 in the neck 5 oi the stud with the fiat bearing 8 facinginwardly, the rotary disk 11 then inserted through the base of the studwith its eccentric projection 13 in the recesses 9 and 10 in the boltand the key then placed in position from the iront of the stud'and itscentral pin made fast to the disk 11 by the nut 21*. The retainingspring 17 is then placed in position in the shallow recess 1S in thebase 4 of the stud and the button as a whole may be secured to asuitable support ior example, the support 25, by means of screws 26, 27,extending through the base 4 and through the opposite ends oi the spring17 into the support.

In operation, the slot 10 in the bolt permits the eccentric projection13 to be turned in one direction only by the pin 22, the latter restingagainst the bottom wall o said slot when the key is turned to its limitin either oi two opposite directions. The nose 16 ofthe retainingspring- 17 will engage the indentation 14 when the eccentric projection13is at one limit of its rotary movement, for instance, to advance theholt, and the other indentation l5 when the eccentric is at the oppositelimit of its rotary movement., ior example, to withdraw the bolt. Whenthe eye oi the curtain llas been passed over the stud and the boltadvanced, no strain on the curtain can exert a pressure on the belt in adirection to release it, as any outward pressure is at right angles tothe direction in which the bolt nieves.

This structure also provides for placing the button complete on thesupport to which the curtain is to he fastened, leaving,T the curtainitseli iree troni any part, or memberol the button and provided simplywith an eye.

The structure is neat in appearance, strong and durable and may bemanipulated easily and quick y.

What l claim is z- 1. A hntton comprising;- a stationary hollow stnd iorreceiving an eye in the curtain, a holt seated in and movabletransversely of the stud and a rotary key and eccentric for operating;the holt'.

2. A hntton comprising a hollow stationary sind i'or receivingv an eyein the curtain, a holt seated in and movahle transversely of the stud,an eccentric mounted in the stud and adapted tio be engaged with theholt for operatine it, and a key mounted on the outer end olf the studand en ;'agg'ed with the eccentric for operating it.
